We have an older shower, with 1×1 tiles on the floor. Some of these, the grout has started to crack, and we want to prevent water damage. However, we've exhausted our renovation budget for the year, and won't be able to do a shower replacement until sometime late next year.

As a temporary hack, could we apply a thin layer of caulk to these grout lines? Would this help?
